内容一致原则:

1.主语中有all, half, most, the rest等, 以及”分数或百分数+名词”做主语时,谓语动词单复数取决于连用的名词.如:The rest of the bikes are on sale today.    剩下的自行车， 今天出售。60%of the apple was eaTen by little boy.   这个苹果的60%都被这个小男孩吃了。Most of the apples were rotten.       大部分的苹果都是烂的。Most of the apple was eaten by a rat. 这个苹果的大部分被老鼠吃了。 2. 不定数量的词组, 如:part of , a lot of , lots of , one of , a number of , plenty of等作主语时, 谓语动词的单复数取决于量词后面名词的数.如:A part of the textbooks have arrived. 一小部分教科书已运到。A part of the apple has been eaten up by the pig. 这个苹果的一部分被猪吃光了。 3. 加减乘除用单数.如:Fifteen minus five is ten . 15减去5等于10。 4. 表示时间, 金钱, 距离, 度量等的名词做主语时, 尽管是复数形式, 它们做为一个单一的概念时, 其谓语动词用单数.如:Ten miles is a good distance. 十英里是一个相当的距离。 5. (1) 通常作复数的集体名词. 包括police , people, cattle 等, 这些集体名词通常用作复数.如:   The British police have only very limited powers.(2) 通常作不可数名词的集体名词. 包括equipment, furniture, clothing, luggage 等.(3) 可作单数也可作复数的集体名词. 包括 audience, committee, government, family, enemy, group, party, team, public 等.如:The committee has/have decided to dismiss him. 委员会决定解雇他。 6. the +形容词/过去分词形式”表示一类人或事物, 作主语时, 谓语动词用复数.如:The injured were saved after the fire.
